Memo to Sean ‘P. Diddy’ Combs: Jessica Alba is engaged to Michael Weatherly. Globe magazine reports Puffy surprised the former Dark Angel hottie on the set of her new movie ‘Honey’. Alba couldn’t figure out why Puffy stopped by, but during a break, he approached her and invited her to lunch, or even dinner. Alba responded, “Sure, if you don’t mind my fiance joining us.” Luckily Diddy’s cell phone rang and he took off. Jessica hasn’t heard from him since.
